Hi,
with Windows 10 I have bumped into this same message repeatedly, in those circumstances:
1. Removing ads from .avi files that are usually 1GB+ in size.
2. Just now trying to splice together two .avi files sized 105 MB and 432 MB.
Kind Regards,
Jochen K.
edit:
I tried to join those two files twice; I just noticed that both attempts produced identical output: a film snippet 2:37 mins long and 20.7 MB in size.
edit 2:
I just loaded another largeish .avi file - and didn't even try to remove the ads, because I noticed something that I remember from all those failed attempts - the blue visualisation of the soundtrack proceeded until it had reached roughly three quarters, then it stopped.
The last time this happened, I...
-...removed everything without the blue sound bar; this worked.
-...tried just to keep that part and remove everything WITH the blue sound bar; this failed with the usual error message,
